Refers to a style of Attic vase painting that appeared in its early form around 475 BCE and ended around 420 BCE, following the flourishing of the Attic Black-figure style. It is characterized by work in Red-figure technique, and later by painting on white ground. It was known initially by a new looseness and freedom in composition, and later by the influence of contemporary sculptural work that was taking place on the Parthenon. It typically includes ambitious compositions on large vases, and, in earlier forms, uses Archaic conventions side-by-side with innovative, free renderings.
